ScriptGen Pro‚Ñ¢ supports Aladdin's Join action atom. To be able to use this feature you'll need Aladdin's Join Installer Engine (available from Aladdin 408-761-6200).
Use the Compression window to tell ScriptGen Pro where your "engine" file is.
All you need to do is "stuff" and segment your files with v3.x of the Stuffit programs. Multiple files may be included in a stuffit archive as long as you do not need ScriptGen
Pro’s ability to specify where those files should go (i.e. they will all go where the archive is set up to go).
The files must be named as xxx.1, xxx.2, xxx.3 where xxx is the unsegmented file name.
P.S. If you purchase Aladdin's atoms, tell them you're using them with ScriptGen Pro!.
